Walsh on standby for Colbert ride

Mark Walsh will partner Colbert Station if Tony McCoy opts to ride Double Seven in the Crabbie’s Grand National at Aintree tomorrow.

Of the JP McManus-owned duo, McCoy has admitted to having a slight preference for the latter, trained by Martin Brassil.

Should that be the case, Walsh, who is used regularly by McManus in Ireland, will get the leg-up aboard Colbert Station, who unseated McCoy at The Chair in last year’s Grand National.
